OK, have done a basic search but have no clue what to really search for. A weird studder/shtter happens when backing into my driveway, kind of feels like wheel slippage, but is not. Happens when turning in reverse, driveway is a slight slope, but not too drastic.. Anyone experience this. Any ideas what it could be. I back into all parking spaces when going to work and stores, and never experienced it, although all of them have been flat ground.

TIA

is this when you are in 4wd?

 

nope, I haven't even had it in 4wd yet, bought in Dec 2019 and very mild winter in the Mid Atlantic this year...

There are quite a few reports of this happening, but only in the F-250 gas trucks. It's something to do with that particular transmission, which isn't shared with the rest of the Superduty line. I don't think anyone has figured out the problem.

 

that is what I got out of reading the other thread.. hopefully it will not cause a big problem, don't tow, just haul heavy stuff sometimes...

 

Welcome to the club. It's happened a few times to me but only when backing a trailer against some resistance like a small incline.There have been no definitive answers why it happens and other then this I have not read of issues with this transmission.

 

My 2017 6r100 did it. Backing up a trailer, up any incline is when it happened to mine regularly. My research lead me to a line pressure issue. I just lived with it.
